Gripping and timely series that echoes movies like The Conversation and Enemy of the State. Callum Turner, Holliday Grainger and Ben Miles are perfect in their roles. However, quite a large suspension of disbelief is required to enjoy it (don't ask how/why in many situations), and unfortunately, the ending was unsatisfactory. Maybe it was tweaked to allow for a second season, but the vague ending with no real payoff was anti-climactic compared to several series that have ended with complicated but clear finales.
